What to do when the GETDEB repository is down

If during an update in either Linux Mint or Ubuntu you get error messages from apt, about failing to fetch data from the GETDEB repository (which happens a lot, I’m afraid), here’s a brilliant solution I found at askubuntu.com. Use a mirror!

Here are the steps:

Comment out your existing sources for GETDEB
Add the following sources instead:

deb http://mirrors.dotsrc.org/getdeb/ubuntu quantal-getdeb apps
deb-src http://mirrors.dotsrc.org/getdeb/ubuntu quantal-getdeb apps

Replace “quantal” with your edition if necessary; also, you can add the games repo just by repeating the above two lines with “games” in the end instead of “apps”.

Import the mirror’s security key:

sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com A8A515F046D7E7CF

Refresh your sources and you’re done:

sudo apt-get update

(Quick Tips) gdebi: “The package may be corrupted”

02/05/2012 / Stratos Laspas / 0 σχόλια

I recently fresh installed Linux Mint 12 (Lisa), which is based on Ubuntu 11.10 (Oneiric). I almost immediately bumped into a problem with gdebi, the graphical package installer. The message I received was:

"Could not open XXXX.deb.
The package might be corrupted or you are not allowed to open the file.
Check the permissions of the file."

After a lot of searching, I found this solution in linuxmint forums. Works like a charm:

[code]sudo apt-get install xz-lzma[/code]

Setting up Debian for Android Development

31/07/2011 / Stratos Laspas / 0 σχόλια

After almost 9 months of beating around the bush, I finally started experimenting with developing Android Apps. I’m using Linux Mint Debian (based on Debian Testing), so after some googling, I used this excellent guide over at howtoforge.com:

Setting Up An Android App Build Environment With Eclipse, Android SDK, PhoneGap (Debian Squeeze)

Of course, I used the latest available version of every software mentioned (binary packages, not .deb as they were somewhat outdated in Testing). The only things I changed during the process of setting up was to edit nss.cfg so that I would not get the “nss initialization” error message on my 64-bit system:

[code]sudo gedit /etc/java-6-openjdk/security/nss.cfg[/code]

and changed its content into the following (thanks to java.io.FileNotFoundException: /usr/lib/libnss3.so error on Debian Wheezy):

[code]name = NSS
nssLibraryDirectory = /usr/lib/x86_64-linux-gnu
nssDbMode = noDb
attributes = compatibility[/code]

I left may main user as owner of /etc/eclipse and I made sure that I used the right java, by:

[code]sudo update-alternatives –config javac

sudo update-alternatives –config java[/code]

That’s all!
